pRU Registers and Bus System
The pRU bus system is connecting the various modules on the FPGA to a common master, the Microblaze Subsystem. Each of the modules is associated with a given BASE-ADDRESS specified in the pRU Control Interface Document. Note that several instances do exist for certain modules. E.g. there are one alpide_data instance for each ALPIDE chip connected to the pRU. To communicate with a specific instance one needs to add an offset of 0x1000 times the instance number to the module base address.
E.g. if you want to communicate with the
- 1st instance: <ALPIDE_DATA_BASEADDR>
- 2nd instance: <ALPIDE_DATA_BASEADDR> + (0x1000 * (2-1))
- 16th instance: <ALPIDE_DATA_BASEADDR> + (0x1000 * (16-1))
